Stiletto,

that is positively brilliant! Why couldn't I think of that!?

Two things: an integral fin and assymetric scaling. Skewed assymetric scaling in fact...

One of the things that was bothering me about these plans was that the reduced scale versions (as well as the Merare 120) had spans that made sense from a surface area and model weight/power plant standpoint but the fuses I had issue with.

All the fuses seemed a touch on the small side and it was progressively worse as you went down in scale. There have been discussions about widening the bodies in order to accommodate the innards better - allow an easier install of engines and nose gear as well as the radio gear. After all the fuse, by design, is quite narrow.

Based on your idea to scale the fuse and wing differently in order to have a more "modern" square 2m pattern aircraft - much like today's widebody models - here's what I've come up with:

Keeping the wing span scalings per the plans posted above (and downloaded by several people), I asymmetrically skewed the scalings for the fuses. It will be more obvious what I mean by skewed asymmetric by looking at the figures below:

Picorare 40" Span (~5% asymmetry)
[ul][*] Wing Scaling Factor, Sw = 40"/65" = 61.5385 %
[*] Resulting Fuse scale = Sw x 55" = 33.8"
[*] Fuse Scaling Factor, Sf = 1.50"/2.25" = 66.6* % (recursive)
[*] New fuse scale = Sf x 55" = 36.7"
[*] New dimensions: Wing = 40" / Fuse = 36.7" / Spinner = 1.50" (exact) / Mains = 1.50" / Nose = 1.25"
[/ul]
The ~5% asymmetry comes from the difference of the fuse (66.7%) and wing scalings (61.5%). I'll get to the advantages of such a scaling shortly (to some it may be obvious).

Nanorare 48" Span (~4% asymmetry)
[ul][*] Wing Scaling Factor, Sw = 48"/65" = 73.8462 %
[*] Resulting Fuse scale = Sw x 55" = 40.6"
[*] Fuse Scaling Factor, Sf = 1.75"/2.25" = 77.7* % (recursive)
[*] New fuse scale = Sf x 55" = 42.8"
[*] New dimensions: Wing = 48" / Fuse = 42.8" / Spinner = 1.75" (exact) / Mains = 1.75" / Nose = 1.50"
[/ul]

Mirare 56" Span (<3% asymmetry)
[ul][*] Wing Scaling Factor, Sw = 56"/65" = 86.1538 %
[*] Resulting Fuse scale = Sw x 55" = 47.4"
[*] Fuse Scaling Factor, Sf = 2.00"/2.25" = 88.8* % (recursive)
[*] New fuse scale = Sf x 55" = 48.9"
[*] New dimensions: Wing = 56" / Fuse = 48.9" / Spinner = 2.00" (exact) / Mains = 2.00" / Nose = 1.75"
[/ul]

Tiporare 50 (~1.5% asymmetry)
[ul][*] Note that a 50 size Tiporare would have about 1.5% asymmetry
[/ul]

Tiporare 65" Span (0% asymmetry)
[ul][*] Dimensions: Wing = 65" / Fuse = 55" / Spinner = 2.25" (exact) / Mains = 2.25" / Nose = 2.00"
[/ul]

Merare 72" Span (~0.5% asymmetry)
[ul][*] Wing Scaling Factor, Sw = 72"/65" = 110.7692 %
[*] Resulting Fuse scale = Sw x 55" = 60.9"
[*] Fuse Scaling Factor, Sf = 2.50"/2.25" = 111.1* % (recursive)
[*] New fuse scale = Sf x 55" = 61.1"
[*] New dimensions: Wing = 72" / Fuse = 61.1" / Spinner = 2.50" (exact) / Mains = 2.50" / Nose = 2.25"
[/ul]
Note the skewness (non-linear, if you will) of the asymmetric scalings - as the scale departs further from the original the asymetry increases.

The beauty of this approach, using fuses that are non equally scaled wrt the wings, is that several things get sorted out nicely:
[ul][*] The fuses have increasingly wider formers wrt the 60 size as one goes down in scale.[*] The fuses can now accommodate engines, nose gear and radio gear more easily.[*] The fuses are scaled to taper into the correct standard spinner size exactly.[*] The fuses should allow longer gear legs, due to the longer nose moment, allowing the use of longer props.[*] The fuses have increasingly longer tail moments as the scale reduces. In order to maximize this, wings would be installed flush with the LE of the wing saddle against F2 (F1 is the firewall - these can also be referred to as FW, FA and FB, as per the plans). The wing saddles would have to be adjusted for the "smaller" (and shorter root chord) airfoils by moving the saddle TE forward thus increasing the tail moment.
[/ul]
This approach has the interesting ramification that as the models get smaller, the nose and tail moment increases which should provide for a smoother aircraft with the more "nervous" smaller sizes. Compared to today's squarer designs, the models of the '80's had relatively short tail moments and it should be interesting to see what improvements, if any, would result from this approach. The changes to Dick's design based on the above would also imply of CG location shift and would have to be carefully assessed before flying the models.

If there's an interest, I could assemble composite plans ("shorter" wings and stabs would be inserted into the new "fuse scale" plans), for each scale, and make them available as an option for those who'd like to give these designs a try.

I'm almost certain I'll be using the new Nanorare fuse scalings for my builds on this thread:

I'll throw my 2c comments on the integral fin concept (very nice Stiletto!) in a following post.

Whew! I'm glad to have gotten that down for reference.
